Solution Overview
Problem
Existing sanitation, cosmetics, and cleaning facilities lack automation and user-friendliness, leading to inefficiencies in water usage and consumable distribution, with high flow rates causing rapid rinsing away of products and increased consumable consumption.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a facility uses high flow rates to ensure adequate water supply, then water delivery is sufficient, but water consumption increases and consumables are rinsed away too quickly
Solution Approach 1:
The outlet unit is divided into multiple nozzles that create separate water jets. These jets collide and atomize to form a spray of droplets, delivering water efficiently while maintaining low overall flow rate. The segmentation of water delivery into multiple streams resolves the contradiction between sufficient water supply and reduced consumption.
Solution Approach 2:
The facility changes the physical parameters of water delivery by increasing water pressure (at least 10 bar, preferably 15-20 bar) and transforming the flow pattern from continuous stream to dispersed spray. This parameter change allows low flow rate operation while maintaining effective water delivery through enhanced pressure and droplet distribution.
2Productivity
If a facility increases water pressure to create spray droplets, then water delivery efficiency improves, but energy consumption increases
Solution Approach 1:
The facility converts the potentially harmful effect of high pressure (increased energy consumption) into a beneficial outcome by using the pressurized water to create atomized spray droplets through nozzle collision. The high pressure enables efficient water delivery and consumable distribution, while the low flow rate compensates for the pressure energy input, resolving the energy-efficiency contradiction.
3Quantity of substance
If a facility uses low flow rates to reduce water consumption, then water savings are achieved, but water pressure must be increased which requires more energy
Solution Approach 1:
The outlet unit segments water into multiple jets that collide and atomize at low flow rates. This segmentation allows the facility to maintain low water consumption while achieving effective delivery through pressure-enhanced droplet spray, resolving the contradiction between water savings and pressure requirements.
4Ease of operation
If a facility lacks automation to simplify operation, then device complexity is low, but water usage and consumable distribution become inefficient
Solution Approach 1:
The facility incorporates a control unit with sensors that automatically monitor and adjust water pressure, flow rate, and consumable distribution. This self-service automation optimizes water usage and consumable efficiency while maintaining ease of operation, as the system adjusts parameters automatically without requiring user intervention. The automation resolves the contradiction between operational simplicity and resource efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The facility reduces water consumption, allows for effective mixing and prolonged contact of consumables with the body or object, thereby enhancing their effectiveness while minimizing waste and optimizing resource use.
Implementation Method 1
the outlet unit of the low through-flow rate facility includes a nozzle set with at least two nozzles, wherein the nozzles are arranged for generating a spray of water droplets at a reduced flow rate. This is done by increasing the pressure of the water and creating two or more jets of water that collide with one another and thereby are atomized, creating the spray of droplets. For this purpose, the water pressure can be at least 10 bar or at least 15 bar or at least 20 bar.
Implementation Method 2

The control unit includes at least one sensor adapted to measure at least one value, a user interface unit adapted to enter at least one set-point and a closed loop control unit configured to adapt an operation parameter of the facility in consideration of the at least one set-point.
